COLLIDING BRANES by Rudy Rucker and Bruce Sterling
“But why call this the end of the universe?” said Rabbiteen Chandra, feeling the dry night air beat against her face. The rollicking hearse stank of cheap fried food, a dense urban reek in the starry emptiness of the Nevada desert. “At dawn our universe’s two branes collide in an annihilating sea of light. That’s not death, technically speaking—that’s a kalpa rebirth.”
Angelo Rasmussen tightened his pale, keyboard-punching hands on the hearse’s cracked plastic wheel. His hearse was a retrofitted 1978 Volvo, which ran on recycled bio-diesel cooking-oil. “You’re switching to your Hindu mystic thing now? After getting me to break that story?”
“I double-checked my physics references,” Rabbiteen offered, with an incongruous giggle. “Remember, I have a master’s degree from San Jose State.”
Rabbiteen knew that this was her final road trip. She’d been a good girl too long. She tapped chewing tobacco into a packet of ground betel-nut. Her tongue and her gums were stained the color of fresh blood.
“The colliding branes will crush the stars and planets to a soup of hard radiation,” she assured Angelo. “Then they rebound instantly, forming brand-new particles of matter, and seeding the next cycle of the twelve-dimensional cosmos.” She spread her two hands violently, to illustrate. “Our former bodies will expand to the size of galactic superclusters.”
Angelo was eyeing her. “I hope our bodies overlap.” He wore a shy, eager smile. “Given what you and I know, Rabbiteen, we might as well be the last man and woman on Earth.” He laid his hand on her thigh, but not too far up.
“I’ve thought that issue through,” said Rabbiteen, inexpertly jetting betel spit out the window. Blowback stained her hand-stitched paisley blouse. “We’ll definitely make love—but not inside this hearse, okay? Let’s find some quaint tourist cabins.”
As professional bloggers, Rabbiteen and Angelo knew each other well. For three years, they’d zealously followed each other’s daily doings via email, text messages, video posts, social networking, and comment threads.
Yet they’d never met in the flesh. Until today, their last day on Earth—the last day for the Earth, and, in stark fact, also for Earth’s solar system, Earth’s galaxy, Earth’s Local Group galactic cluster, and Earth’s whole twelve-dimensional universe shebang.
The end was near, and Rabbiteen didn’t care to watch the cosmos collapse from inside her cramped room in her parents’ house in Fremont. Nor did Angelo want to meet the end in his survivalist bunker in the foothills of the Sierras near Fresno—a bunker which, to untrained eyes, resembled an abandoned barn in the middle of a sun-killed almond farm.
So, after a dense flurry of instant messages, the two bloggers had joined forces and hit the great American road together, blasting one last trump from the hearse’s dirge-like horn, a mournful yet powerful blast that echoed from Rabbiteen’s parents’ pink stucco house and all through the table-flat development of a thousand similar homes.
Chastely sipping biodiesel through the apocalyptic traffic, they’d made it over Tioga Pass onto Nevada’s Route 6 by midnight. They were out well ahead of mankind’s last lemming-like rush to universal destruction....
